Bambu Lab, the Chinese 3D printer manufacturer, has announced the availability of its latest 3D printing material, the high-speed PETG HF filament, the HF standing for High Flow. This new filament is intended to increase printing speeds while maintaining high-quality results, catering to both hobbyists and professionals.
The PETG HF filament is now available and promises improved performance in a variety of applications, particularly those requiring strength and durability.
What are High-speed Filaments?
High-speed 3D printing filaments are specifically designed to support rapid printing speeds while maintaining the quality and integrity of printed objects. These filaments, which include high-speed PLA, PETG, and ABS, have improved fluidity and faster melting and cooling properties, allowing for faster layer deposition and better interlayer adhesion.
Simply owning a fast 3D printer does not guarantee high-speed printing efficiency. The filament is important because standard filaments can cause problems such as clogging, poor layer adhesion, and warping at high speeds. High-speed filaments are intended to alleviate these issues, ensuring print quality even at higher speeds. They accomplish this by optimising molecular weight and flowability, lowering resistance during extrusion and ensuring consistent feeding through the hot-end.
This combination of high-speed filaments and capable printers significantly reduces print times, making it ideal for prototyping, large-scale production, and applications requiring both speed and precision.
High-speed PETG HF Filament

The PETG HF filament is designed for high-speed printing, allowing users to complete projects more quickly without sacrificing quality. This filament is ideal for creating strong parts that can withstand stress and high temperatures.
The company claims that it will print as easily as PLA, the most commonly used printing material.
Key features of the filament
Enhanced Speed and Efficiency
One of the most notable features of the PETG HF filament is its ability to support faster printing speeds. It prints twice as fast as regular PETG. This is accomplished with a formulation that reduces the risk of clogging and ensures a smooth extrusion process.
Durability and Strength
The filament maintains PETG’s toughness and flexibility, making it ideal for functional parts. It is particularly useful for designing components that must be both durable and flexible.
Applications and Benefits
The PETG HF filament’s versatility makes it suitable for a wide range of applications, including engineering parts and custom tools. Its properties enable both creative and practical applications, striking a balance between ease of use and performance.
